Today, I made over 30 Sigil builds with the About dialog test. I think this code works:

Code:

    setWindowFlags(windowFlags() | Qt::CustomizeWindowHint);
    setWindowFlag(Qt::WindowMinimizeButtonHint, false);
    setWindowFlag(Qt::WindowMaximizeButtonHint, false);
    setWindowFlag(Qt::MSWindowsFixedSizeDialogHint, true);

I would bet on Qt 6.10.x, which started inheriting more system flags in Windows, and if they are not overwritten, the system adds active Min/Max.
